The following steps are now required after using ./rename_roll.sh...

  - Download or otherwise create src/${NEWNAME}/${NEWNAME}-1.0.tgz
  - Upload src/${NEWNAME}/${NEWNAME}-1.0.tgz to the DL.SERVER listed in 
    src/${NEWNAME}/pull.mk
  - Record size and git hash of src/${NEWNAME}/${NEWNAME}-1.0.tgz in 
    src/${NEWNAME}/binary_hashes per the instructions in src/${NEWNAME}/README.md
  - Perform the desired [optional] steps listed below
  - Initialize the new git repository
  - Make at least one commit to the new repository
  - Add annotated tags for the supported Rocks versions to the new repository
    so that version.sh will provide a 'sensible' version number for the new
    roll.

While not required, you should rename this directory ${NEWNAME}-roll to avoid 
confusion and, optionally, perform the following additional changes...

  - Remove USING.md, rename_roll.sh and src/${NEWNAME}/README.md
  - [Optionally] move gen_hash.sh to a new location (ie. ~/bin) or remove it.
  - If you are not going to populate the default Rocks usersguide then remove 
    the entire src/usersguide directory and remove the
    <package>roll-${NEWNAME}-usersguide</package> entry from nodes/${NEWNAME}-base.xml
